'MACHINE non. SEWING oN BUTTONS..

Application filed September Buttons of all kinds are sold sewn on tocards, the number of buttons in 'a ro'w and the distance between therows diii'ering ac cording to the size of the buttons. This differencein the number of buttons and in the distance between the rows was one ofthe difficulties which has hitherto prevented buttons being sewn on tocards entirely by Inachinery.

Consequently in the methods at pr sent in use the buttons had to beplaced one by one by hand in correct position on the card and had to beheld there, until the sewing operation by the sewing machine had been'started.

The present invention provides an arrangement which enables the buttons'tobe sewn on entirely by machinery, without the number of buttons tothe row or the distance between the rows causing any diiiiculty'andwithout the necessity of 'each button being held in position by hand.The device isf-not only suitable for sewing buttons on to cards, butalso forse'wing single buttons or rows of buttons on to woven fabricsand the like.

Provision is made for conveying the buttons automatically from amagazine to the pla-ce where they are to be sewn on, the Varrangementbeing such that, should button be in a wrong position or should nobutton be forthcoming, the apparatus is automatically thrown out ofaction, so that the person Vattending to it must intervene.

The invention is illustrated by way of example in the accompanyingdrawings, in' which- Figure 1 is a vertical longitudinal sect-ionthrough the device. p

y Figure 3 a plan view of a detail to :an enlarged scale and Figure 4 afront elevation of this detail.` According to the invention in a machineframe 1, in which the various parts of the 2 is mounted so as to becapable of sliding therein. For this purpose a guide 3 is provided, onwhich it slides easily for instance with the aid of balls 4. The slideis traversed by means of a lever 5 ypivoted at a` point 6 on the base ofthe machine' and connected to the lslide by thel link 7. On the lever 5is a roller 8, which coacts with acafm disc 9 on a shaft 10. As theslide must be moved intermittently, a star wheel llis provided inA theactuating' mechanism Vfor the sewing mechanism 1a are journalled, aslide 2s, 1925.A 'serial No. 58,170.

cam disc 9, in which star wheel a pin 12 on 'a disc 13 engages. The starwheel is in operativeconnection through toothed gearing or the like 14,15 with the shaft 10 of the cam disc 9 and the disc 13 is driven yin anysuit.- able manner from a main' driving wheel 16, for instance throughgear wheels 17, 18 and bevel wheels 19, 20. This 'arrangement providesfor the sliding motion required for the sewing on of the separatebuttons one behind the other in a row.

For fixing the card on the slide, bars 21 with guiding grooves areprovided, into which the car 22 is inserted and which allow of the cardbeing displaced in a direction at right angles to the direction ofInouon of the slide.

The Vfollowing arrangement is provided for .advancing the card or othersupport after a row of buttons have been sewn on:

In the slide on a shaft 23 a long pinion 24 is rotatably mounted. Onthis shaft are fixed wheels 25', 26 with sharp teeth, which are adaptedto get a grip of the card or other support with these Vteethrand, onbeing rotated, to feed the same forward. The pinion v241nay be connectedto the. shaft 23 through either of two couplings 27 and 28, which ac tinv opposite directions. The inion can be displaced laterally by aresilient arm29, whereby 'either the coupling 27 or the coupling'28 canbe Caused to engage.

Normally two springs 30 vand 31 keep the arm 29 in such a position thatneither of the two couplings 27 and 28 is in engagement. The pinion 24is turned by means of a toothed sector 32, which meshes with itV andwhich is operated by a cranked lever 33, which is connected to it, froma cam .34, the' rotation of the" gripping wheels 25 and 26 onlyjtakingplace in one direction, when the couplings "are in engagement.

As long as the buttons of onerow are being sewn on, the arm 29 andconsequently the pinion `24 is in its middle position, so that,

while it is turned forwards and baclwvardsv through the motion of thetoothed sector 32, it does not transmit this motion to the grippingwheels 25 and V26. As soon as the last button has been sewn on and theslide has therefore reached the end of its travel, the arm' 29 strikesagainst a yyielding stop 35 on a lever 36. This causesthe arni '29 toswing aside and oneof the couplings, in this case the coupling e7, toengage, so that the fnotion of the pinion derived from the 'sector 32 istransmitted to the gripping wheels 25, 26 and the cardor other supportis displaced by the distance between the rows of buttons.' The iirstbutton of the new row is sewn on and, as the slide moves baclr under theaction of the cam disc 9, the arm 29 ceases to engage with the stopmember 35, the pinion 24 is unc-oupled and there will be no furtherdisplacement of the cards, until 'the slide on reaching the end of its.traversing motion strikes against another stop 'member 37. ihis is thecase, when the last button of the next row has been sewn on. In thiscase the leverx29`is thrown over in the other direction and the coupling28 caused to engage, whereupon the card is again fed forward by thedistance between the rows of buttons and the cycle of operations isrepeated. The stop members 35 and 37 are mounted yieldingly in the arms36and 40, springs'38 and 39 being provided for this purpose, so that,even when the arm 29 rests against one of them duringthe tok and froymotion of the toothed sector the couplings 27 and 28 can engage. Bymeans of a bar 41 connecting the two arms 36' and 40 the distancebetween the stop members and thereby the Icommencement of the forwardfeed of the card can be accurately adjusted. The amount of forward feedof the card is adjusted for by an adjusting screw 42' Awhich accordingto its position allows thetoothed sector 32 to be moved througha greateror smaller y'angle and to transmit a greater or smaller angle ofrotation to the pinion.` n

For holding the button in position, when being sewn on, albuttonholder43 is provided,A which is raised and' lowered by a` cam disc 44.On a partof the Amachine adjacent to the slide 2 a` stop member 45 inthe form of a baror an anglek piece is provided,`

againstwhich thelbuttons are placed by the person attending to themachine. V`vA feed arm 46 is provided, which has two downwardly directedteeth 47, the object of which isl to enter the holes inthe button, gripthe latter in this ymanner andy bring it forward to the needle in thecorrect position for sewing. Ihe feed arm 46 is pivoted to a lever 43, abar 49 being provided'on the said lever, which imparts a raising andlowering kmotion tothe feed arm. In the button holder 43 is a recess 50,through which the end of the feed arm 46 can pass for bringing'thebutton into the correct position immediately below the button holder. lA

rlhe ldevice just described takes hold of the button resting against themember 45 by the teeth '47 entering the holes in the button and, on thelever 48l performing a swinging motion', moves the button under 'thebutton holder, whereupon the latter descends and grips the'button.vv`The feed arm is, thereupon raised and moved aside for'fetching t-henext button.

thel attendant will find it easy to hold the f button in readiness atthis place.
